Here is a look at some brain facts that will
amaze your brain!!!
* We have approximately 70,000 thoughts per day, although many will be the
same ones looping round and round on our grooved cranial highway.
* The brain is very poor at concentrating for long periods of time and
needs to clear it’s head so to speak about every 90 minutes or so.
* An adult human’s brain weighs 3 pounds. The heaviest on record
weighed 5 pounds.
* The human brain is over three times as big as the brain of other mammals that
are of similar body size.
* Despite weighing only about 3 pounds, the brain consumes as much as 20% of the
oxygen and glucose taken in by the body.
* 15-20% of all blood pumped out of the
heart goes directly to the brain.
* Brain is composed of 75 to
80% water. Dehydration can affect proper functioning of brain.
* The right side
of the brain interacts with the left side of the body, and vice versa.
* A person who
is "left-brained" is often said to be more logical, analytical, and
objective, while a person who is "right-brained" is said to be more
intuitive, thoughtful, and subjective, but this has been proved to be a myth.
* Even if you
consider yourself a left-brained person, your brain will still switch over to
the right side every 90 to 120 minutes and then back again.That’s why even left-brained people can have times of the day when they
are more creative and right-brained people can sometimes get their taxes in
order.
* The brain itself is incapable of feeling pain.
Once the skull is opened it is possible to operate on the brain with the
patient awake.
* It is a myth that humans use only 10% of their brains.Modern MRI scans proved
that people use just about their entire brain even when they are sleeping.
* The human brain is capable of executing 10 quadrillion calculations per
second--no computer today can match the human brain!
* If you were to measure your brainwave activity you wouldn’t see any drop
off when you’re asleep.The brain is more active at night than during the day.
* By age 18, the human brain stops growing.
* After age 18, the human brain begins to lose more than 1,000 brain cells
each day. Do not fear, since the fully developed brain has over 100 billion
cells, at the rate of losing 1,000 cells each day, it will take 300,000 years
before your brain is out of cells.
* Nerve Impulses from your brain and back travel at over 400 km/hr (250
mi/hr).
* The higher your IQ, the more you dream.The average person has at least
seven dreams a night.
* You can’t feel
your own tickle either. The brain is smart enough to
neutralize the sensation. The cerebellum sends a signal to rest of the brain of
your intentions and as a result the sensation is ignored.
* Men's brains
are indeed bigger. Does this mean they're smarter? Not necessarily,
as in women's brains, the neurons are packed in
tightly, so that they're closer together and more compact.
* Researchers
from Harvard found that parts responsible for problem-solving and
decision-making, and for regulating emotions, were larger in women.
* In
men, the parts of brain involved in space perception, and which regulates
sexual and social behavior, were larger.
* Men also have
approximately 6.5 times more gray matter in the brain than women. Women have
about 10 times more white matter than men, which
may allow a woman's brain to work faster than a man's.
* Reading out loud to
kids accelerates their brain development.
* Our brain never
loses the ability to learn and change because it’s effectively plastic and
constantly rewiring itself.
* Our brain doesn’t
record memories like video. It takes snapshots of the more important bits and
then when you recall the event it guesses what happened in between based on
prior experience.
